Hello, We just started working with an updated design which now uses an AD5724R but it does not work properly. I cannot set output voltages, especially negative voltages, but the previous design which used an AD5724 with an external reference works just fine. How are the 2 parts different from a software perspective? Thank you for any insight or suggestions. Steve
Thank you I see exactly the issue with the PUREF bit in the Power Control Register. That bit was set for '0' for the AD5724 and now must be set to '1' with the AD5724R since we want to use the Internal Reference. We made that change and the DAC is working. Thank you for your support!
